Summary

Vulnerability Details

DESCRIPTION: WebSphere Application Server could be vulnerable to a cross-site request forgery, caused by improper validation of portlets in the administrative console. By persuading a user to visit a malicious Web site, a remote attacker could exploit this vulnerability to obtain sensitive information. CVSS:

DESCRIPTION: WebSphere Application Server using WS-Security and configured for XML Digital Signature using trust store, could allow a network attacker to gain elevated privileges on the system, caused by improper checking of the certificate.

DESCRIPTION: WebSphere Application Server could allow a cross-site scripting attack, caused by improper validation of input in the UDDI Administrative console. A network attacker could exploit this vulnerability using a specially-crafted URL to inject script into a victim's Web browser within the security context of the hosting Web site.

DESCRIPTION: WebSphere Application Server could allow existing users to gain elevated privileges on the system caused by incorrect Administration Security roles being assigned after migration from version 6.1 or later.

NOTE: If a migration from WebSphere Application Server Version 6.1 or later has already been performed, all users designated with "adminsecmanager" (Administrative Security Manager) role need to be evaluated to determine if they should have both "admin" role and "adminsecmanager" role. Some users may not need both designations and the privileges should be removed accordingly.

REMEDIATION: The recommended solution is to apply the Fix Pack or PTF for each named product as soon as practical
Fix: Apply a
Fix Pack or PTF containing this APAR PM92313, as noted below:

For IBM WebSphere Application Server

For V8.5 through 8.5.5.0:

Apply Fix Pack 1 (8.5.5.1), or later.

For V8.0 through 8.0.0.7:

Apply Fix Pack 8 (8.0.0.8), or later.

For V7.0 through 7.0.0.29:

Apply Fix Pack 31 (7.0.0.31), or later.

Workaround(s): If a migration from WebSphere Application Server Version 6.1 or later has already been performed, all users designated with "adminsecmanager" role need to be evaluated to determine if they should have both "admin" role and "adminsecmanager" (Administrative Security Manager) role. Some users may not need both designations and the privileges should be removed accordingly.
Mitigation(s): none

REMEDIATION: The recommended solution is to apply the Fix Pack or PTF for each named product as soon as practical
Fix: Apply a
Fix Pack or PTF containing APAR PM93323 for IBM WebSphere Application Server Full Profile or APAR PM93944 for IBM WebSphere Application Server Liberty Profile, as noted below:

DESCRIPTION: WebSphere Application Server could allow a cross-site scripting attack, caused by improper validation of input in the Administrative console. A remote attacker could exploit this vulnerability using a specially-crafted URL to inject script into a victim's Web browser within the security context of the hosting Web site.

DESCRIPTION: IBM WebSphere Application Server may be vulnerable to cross-site scripting, caused by improper validation of input in the Administrative Console. A remote attacker with Administrative authority could exploit this vulnerability using a specially-crafted URL to inject script into a victim's Web browser within the security context of the hosting Web site.

DESCRIPTION: IBM WebSphere Application Server could be vulnerable to a denial of service, caused by improper handling of requests by a web services endpoint. By passing a specially-crafted request, a remote attacker could exploit this vulnerability to consume available resources.
